<P>PROBLEM TO BE SOLVED: To provide a link device for the treating instruments and the instruments which are ideal for the operation of the endoscopes by achieving the finer diameter of the insertion tube parts. <P>SOLUTION: Multi-freedom forceps (treating instrument)1 are used as a soft treating instrument together with the endoscope. The multi-freedom forceps 1 have a link device 2 for the treating instruments to be inserted into a body cavity. The link device 2 for the treating instruments has an insertion part 3 extended tubularly, a treating part 5 connected to the forward end of the insertion part 3 and a manipulation part 6 for manipulating the treating part 5. In a deviation link member 15, a base end part side 15a is securely connected to the first operation shaft member 7 and the forward part 15b side as the side of the treating part 5 is formed being extended parallel with the first operation shaft member 7 at the position which is located inward from the outer circumferential surface 3b of the insertion part 3 being deviated outward diametrically from the center shaft CA of the first operation shaft member 7. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
